EDWARD P. BULLARD, JR., OF BRIDGEPORT, CONNECTICUT, ASSIGNOR TO THE BULLARD MACHINE TOOL COMPANY, OF BRIDGEPORT, CONNECTICUT, A CORPORATION OF CON- NECTICUT.

My invention relates to improvements in vertical turret lathes having both a crosshead and a side-head, and comprises such a novel construction and arrangement of the heads'and their supports that a machine embodying it will have a greater range of cut, perform a lar er variety of operations, and

c more readily adjusted 'to the work than any machine of this type at present known to me.

The main object of my invention is to construct a compact machine which will not only include withln the S00 e of its operations all those now performed y boring mills, turret lathes, and engine lathes, but one on which the work can be handled more advantageously and the various operations performed more conveniently and expeditiously than on those machines. To a limited extent this object has been attained by machines now in use, among which may be mentioned the vertical turret lathe described in Letters Patent of the United States No. 683,592,

issued to me Oct. 1, 1901. In the latter machine the cross-head and side-head are mounted upon stationary guide-ways placed in d'ifierent planesand the tool of each head is adapted to be fed crosswise or lengthwise of the axis of rotation of the table. The utility of machines of that general design, however, is limited in that the tool of neither head can be fed at an oblique angle to the table, a requirement demanded by a large class of work; the cutting capacity of the side tool is also limited in that the side-head,

- in its upward travel, strikes the cross guideways before its tool has reached a height from the table corresponding to that of the underside of the uide-ways, which ways should, in a compact y designed machine, determine the range of vertical cut; and the efficiency of such machines, from the standpoint of quick adjustability of the cutting tools of 2 each head to the work, is'restricted in that the heads are adjusted lengthwise of the Specification of Letters Patent.

,' work independently instead of conjointly and 1 independently.

Included in the main object of my inven-.

6 tion, therefore, are the following specific objects, the fulfilment of which wholly eliminates the restrictions and limitations above i mentioned, to wit:'to so design the two= 5' 0 heads of the machine that the cutting tool{ of each will have a transverse and longitudinal movement the full axial and radial swing of the rotary table, and to so combine them that their respective cutting tools may anywhere within their sphere of operation,

or lengthwise of the axis of rotation of the may be conjointly used on a crosswise or' lengthwise roughing cut, thus accomplishing accomplished by either tool alone; to so design each head that its cutting tool may befed at any desired angle to the table, and to so support them that they may be either conjolntly or inde endently adjusted lengthwise of the axis 0 rotation of the work supported upon the rotary table; to so design the machine that the side-head and its feed mechanism will be entirely independent of the cross-head and its feed mechanism, and thereby capable of being added to the machine at any future date, thus providing a machine that can be constructed and sold either as a cross and side-head machine completed, or as a cross-head machine alone, with the option in the purchaser of the single head machine of purchasing the side-head -and adding it to the machine at a later date if his special requirements demand it: and :iinally to so design the machine that it may be built and placed on the market ata comparatively low figure.

In illustrating my invention I have purposely omitted certain details that are common to all machines of this class and have but partially outlined certain features which are reserved for separate applications.

With the above and other minor objects in view my invention resides and consists in the novel construction and combination of parts shown upon the accompanying seven sheets of drawings which form a part of this specifil cat n, and upon which similar characters of be brought into close contact with each other and in that position fed conjointly crosswise work, whereby the two tools for instance by their joint use twice as much as could bereference denote like or corresponding parts throughout the several figures, and of which Figure 1 shows a front elevation of my machine complete, both the cross and side-heads being shown in a position of rest.

also a front elevation, but shows the heads shifted into operative position for cutting a gear blank carried by the rotary work-holder. Fig. 3 is a side elevation of the machine.

Fig. 4 is a front elevation of the adjustable double rail seen in the preceding views and u on which .both the cross and side-heads are a justably mounted. Fig. 5 is a side view of the double rail, but with the gears shown in 5 dotted outline; and Fig. 6 a plan view of the same. Fig. 7 is a detail cross section view of said rail taken on line 77 of Fig. 4. Fig. 8 is an enlarged front elevation of the side-head seen in Figs. 1, 2, and 3. Fig. 9 is a vertical cross section through said side-head taken on line 9 9 of Fig. 8. Fig. 10 is a horizontal cross section taken on line 1010 of Fig. 8, and illustratesthe shiftable clutch mechanism for actuating the side-head laterally, or its tool slide crosswise at whatever angle it may be adjusted. Fig. 11 is a detail vertical section taken on line 11 of Fig. 8. Fig. 12 is a detail side view as seen from the right of F Fig. 13, and illustrates the clutch mechanism. Fig. 13 is an enlarged rear elevation (see arrow a Fig. 3) of one of the changeable speed mechanisms inclosed, by means of which the cross-head and side-head, and their respective tool-slides, are operated; and also shows in vertical section the reversing device for said speed-changing mechanism. Fig. 14 is an enlarged detail sectional elevation of certain gears and shafts employed in driving the speed device and heads above mentioned, the section being indicated by line 14 of Fig. 3.

An examination of Figs. 1, 2, and 3 plainly shows that the main elements of my machine comprise aframe A, a rotary table or workholder F su ported by the frame, a tool carrying crossead and side-head carried upon the transverse and lateral arms respectively of a right angled cross-rail B mounted upon guide-ways A A and guide-bracket A of the frame, and mechanism for operating the table and heads. The construction of each and the manner in which they are combined to attain the objects above set forth I wil describe in detail.

E5 The cross-head comprises a saddle-Q having ways on its rear face adapted to fit the transverse guide-ways Q and an annular shaped recess U on its front face, a guide- .plate T swiveled on the saddle, a tool-slide S mounted in guide-ways of the swiveled plate, and a rotatable turret tool-head J mounted uponthe slide and adapted to carry the cutting tools. The swivel guide-plate T is securely clamped to the saddle by means of four shaped bolts and binding nuts U, the

Fig. 2 is dle Q and the other end of which projects outside the rail and is adapted to receive either a pull-gear R or a crank handle. The 30 cross-head tool-slide S is actuated by means of mechanism comprising a splined feed-rod R ournaled 1n the crossra1l, one end of which passes through a worm R carried by the saddleQ and the other end of which pro- 5 I jects beyond the rail and is also adapted to receive either said pull-gear R or said crank handle; a worm-gear R meshing with the worm, and a pinion S meshing with a rack attached to the tool-slide S. At the end of the rail is an intermediate gear N which is revolved by means of a speedchanging mechanism to be hereafter described, and the placing of pull-gear R on the feed-rod R or feed-screw Q, on either of which it meshes 5 with the intermediate gear N, determines, when the gear N is revolving, whether the cross-head or the cross-head slide-shall be operated. Either of them may also be oper ated by hand by means of a crank slipped onto the projecting ends of the feed-rod or feed-screw. It is thus apparent that .the cross-head may be actuated either to the right or left on the transverse guide-ways Q and that its tool-slide may be actuated per- 1 5 pendicularly towards or away from the table or at any angle thereto, either by power or hand.

For the purpose of relieving the slide S of its dead weight and thus render easy its no movement in the guide-w ay of the plate T it is counterbalanced by means of a weight V suspended by a strap attached to the pulley V of the shaft V. This shaft is journaled in a bracket attached to the cross-rail and is operatively connected by suitable gearing (not shown) to the slide and the weight of the latter thereby neutralized. The method of combining these parts being one which I shall cover by a separate application I deem it proper to omit the details of construction in this application, and merely describe it in a general way as above set forth.

The side-head which is shown in detail in Figs. 8, 9, and 10 comprises the same ele- 12-3 ments as the cross-head, namely; a saddle U having guide-ways on its rear face registering with vertical guide-ways Y and an annular shaped recess on its front face, a swivel guide-plate 72. mounted on the saddle crank, whereby the rod and provided with guide-ways g on a right angled extension, a tool-slide g mounted on the guide-ways and a tool-head J mounted on the front time of the tool-slide. The swivel guideplate is clamped to the saddle by means of bolts and nuts h in the same manner as the cross-head saddle and its plate are clamped, and it may be clamped at any desired angle thereto, thus permitting the tool-slide to be fed parallel to the face of the rotary work-holder F or at any desired angle to said face.

The side-head is actuated along the vertical ways Y (Fig. 1) and its tool slide 9 upon the angle plate guide-ways g by means of the following described mechanism :W is a stationary screw attached to the vertical section of the right-angled cross-rail B, and b is a splined rod journaled in said section and 'operatively connected to a driving rod 6 by means of spiral gears b and 1; (Figs. 9, 10, 11). The outer end of b is adapted to receive a pull-gear c, which meshes with an intermediate two-ste gear N driven by a train of gears hereafter described, or a handmay be revolved by power or by hand. The splined rod b is operatively connected to the horizontal rod d by means of bevel gears c, a, the former being keyed to the rod 6 but carried by the saddle U, and the latter being fastened to rod d. Running loose upon the hub of gear a is a clutch spur-gear a which meshes with a spur-gear X. The latter gear is driven fast upon the hub of a bevel gear X which revolves loose upon a stud a, (Fig. 11) and meshes with a bevel-gear X out upon a nut W of the stationary screw W. The latter gear is shouldered in a long bearing W of the saddle and its revolution causes the saddle to rise or fall on the vertical ways depending upon the direction in which it is revolved.

Upon the horizontal shaft (1 (Fig. 10) is a clutch sleeve 6 having a thread 6 out upon its outer surface which meshes with a wormgear e. The latter is keyed to a vertical shaft f (Fig. 9) and carries at its upper end a pinion f which meshes with a rack f attached to the tool-slide g. Between clutchgear a and clutch-sleeve eis a slidable clutch d which is keyed to the shaft d and pinned" to a knob-ended shift-rod d slidable within the shaft (1 and by means of which it is shifted into driving contact with clutch-gear a or clutch-sleeve e.

If the intermediate two step gear N is revolving and the clutch d is thrown into contact with clutch-gear a the latter will set in motion the gears that o erate the nut W upon the vertical screw TV and cause the side-saddle and conse uently the side-head to travel along the guid -ways of the vertical rail, and if the clutch is thrown into contact -with the clutch-sleeve e the latter will revolve with bevel-gear a, and set in motion the gears that operate the rack-pinionf' and cause the tool-slide g to travel along the Ways of the swivel-plate and at whatever angle to the table it may be set. The direction of travel in each case will depend upon the direction in which the intermediate gear N is revolving.

By drawing the pull-gear 0 out of contact with gear N and forcing the clutch (1 into contact with spur-gear a the side-head may be raised or lowered upon the side-rail by means of a hand-wheel g which is keyed to the rod d; by forcing the clutch into contact with clutch e of the threaded-sleeve e the tool slide 9 may be actuated either forward or backward.

The side head is counterbalanced by means of an attached rope tcarried up over suitable pulleys t and supporting-a weight i, as shown, (Fig; 3).

In order to attain one of the objects of my invention, namely, a method of conjointly and independently adjusting the two heads lengthwise of the axis of rotation of the work, the guide-\vaysQ and Yupon which the heads travel are preferably placed upon a rightangled or '1 shaped cross-rail B which is adjustable upon the vertical guide-ways A A of the frame and guide bracket A This rail is preferably made in two parts, for a reason to be hereafter explained, one part consisting of the transverse sectionwhich carries the transverse-ways Q and the other part consisting of the dependent section which carries the lateral-Ways Y. They are preferably united by a lap and butt joint, as clearly shown in Fig. 5, the transverse section having a rabbeted extension on the lower side of its right hand end and the lateral section having its up er end rabbeted to fit said extension and t e two being clamped together by screws P.

The lateral-ways Y are beneath and preferably in the same plane with the transverseways Q, a sufficient space being left between them to permit the cross-headv saddle Q to ass. p The conjoint adjustment of the heads and rail upon the frame is accomplished by the following means, to wit:N 1s a hand wheel keyed to the outer end of a horizontal shaft 0 which is connected to a vertical screw P by means of miter-gears O O. The latter asses through a nut P fastened upon the back of the transverse section of the crossrail, and consequently a revolution of the hand wheel X will raise or lower the combined rail, and also the cross-head and sidehead carried thereby, from or toward the rotary-table or work-holder F. By combining the means thus offered for conjoint adjustment of the heads lengthwise of the axis of rotation of the table of the machine with the means for adjusting them separately upon their respective guide-ways the tool attain some of the other objects set forth in -work than if the heads were only adjustable whichdistance I term the axial swing of the table.

1 also has the same range of cut by reason of will permit said cutting tool to travel from of each can be more readily adjusted to the separately.

The above mentioned arrangement of the j transverse and lateral-ways in substantially the same plane, in combination with the de- I sign of the cross head and side-head, in the latter of which the tool-slide is placed on to of a right-angled extension of the swive plate J (Figs. 3, 9) is'one of the novel features of my invention and by means of it I the preamble. By bringing the lateral ways forward into substantially the same plane as the transverse ways and by offsetting the tool-slide g of the side-head, the slide, as its head is moved into its highest osition with the saddle U in contact with t 1e transverse I section of the rail, will project over and clear the transverse ways and thus permit thecutting tool carried in tool-head J to have a lateral range of cut corres onding to the distance from the rotary tab e to the under side of the transverse. section of the cross-rail,

The tool-slide g is also adapted, as shown in Fig. 1, to radial adjustment crosswise of the table a distanc'eexceeding the radial distance from the axis of the table to the lateral section of the cross-rail, which distance I term the radial swing of the table. The tool of the side-head is thus adapted to out either the full radial swing of the table or the full axial swing. The cross-head tool the fact that the tool-slide S is adapted to vertical adjustment a distance that will permit a cutting tool of the turret-head J to travel from the rotary table to a height above the table corresponding to the height of the under side of the transverse section of the cross-rail, which section determines the axial swing of the table, and the saddle Q is adapted to transverse adjustment a distance that the axial line of the table to a line further removed from the axis of the table than the inner edge of the lateral section of the crossrail, which edge determines the radial swing of the table.

It is thus apparent that on certain crosswise cuts or cuts lengthwise of the axis of rotation of the table the cutting tool of either head may be used, and it is also apparent that they may be brought into close contact with each other and in that position fed conjointly crosswise or lengthwise of the axis of I rotation of the table anywhere within the cutting s ace, which space is bounded on two sides y the axial line of the table and a line at the same distance therefrom as the inner edge of the lateral section ofthe crossrail, and on the other two sides by the table itself and a line at the same distance therefrom as the lower edge of the transverse section of the cross-rail. This ada tability of the heads whereby the tool of eit er may be fed. crosswise or lengthwise of the axis of rotation of the table the full axial or radial swing of the table, or at any desired angle thereto, or conjointly on the same or different crosswise cuts or cuts lengthwise of the axis of rotation of the table is novel and of special value in a large variety of work. By means of it the tools of the cross-head can perform not only all the operations required on the top of the work carried by the rotary table, and the tool of the side-head not only all the operations required on the side of the work, but, if necessary, both tools can also operate on either the top or the side of the work, thus securing advantages incidentto machines having two cross-heads or two side-heads; or the cutting tool of each head may be brought close together, one having a slight lead over the other, and fed conjointly on combined roughing cuts crosswise or lengthwise of the axis of rotation of the tab e and thus accom lish by their joint use twice as much as cou d be accomplished by the use of one cutting tool alone.

The construction of the two heads and their arrangement upon the cross-rail having been described, a description of the driving mechanism by which the table or workholder F and the heads are operated will now be given.

The main driving pulley B (Fig. 3) of the machine is situated on the left hand side and to the rearof the frame and keyed to a shaft B. The latter supports a cone of speed gears C which meshes with a reverse cone of speed gears C running loose on shaft 0, anyone of which may be locked to said shaft by means of a clutch o erated by a handle Shaft C is operative y connected to shaft D by means of miter-gears D D and the latter shaft to the perpendicular shaft E by asecond set of miter-gears E E. The shaft E carries a pinion F which meshes with an internal spur-gear carried by the rotary table. It is thus apparent that the operator, by looking a gear of train C to shaft 0 by handle 1', may cause a revolution of the driving pulley B to be imparted to the rotary table F and the latter rotated on its Vertical axis.

For the purpose of operating the two heads along their respective guide-ways and the tool slide of each at any angle to the table at which it may be set a train of mech anism is led off from shaft D (Figs. 3 and 4) by means of'a worm G which is keyed to said shaft and which meshes with a worm-gear G keyed to a shaft G. The latter is o eratively connected to a vertical shaft by means of miter-gears H H. Between shaft H and the intermediate gears N N on the right hand side of the cross-rail, one of which N meshes with gearR slipped onto either rod R or feed-screw Q and the other of which N 3 meshes with pull-gear c slipped onto rod 6 are two sets of reversing and change speed mechanism I and J, each inclosed in suitable casings; The two sets of mechanism are alike in construction and I will therefore use the same reference characters to designate duplicate arts and describe in detail but one. Re erring there- 10 fore to Fig. 13 it will be seen that to the shaft H is keyed a collar I that is free to move up or down upon the shaft, and covering this collar is a sleeve I that is clamped to said collar by means of a screw K. To the upper 15 end of this sleeve is keyed a movable clutch member K, which is operated by a common form of lever K (Fig. 12) whereby said clutch member and sleeve, together with the collar I before mentioned, may be shifted 2 upor down on the shaft and thrown into engagement with either the clutch face of the upper bevel-gear L or the lower bevel-gear L. Both of these gears mesh with a large bevel-gear L and drive its shaft M, the direction of revolution obviously depending upon which of the bevel-gears is the driver.

The shaft M is connected with the shaft M by suitable gears of varying sizes,. and a this shaft in turn is likewise connected by varying-sized gears with the third shaft l\ that carries an extra gear N which meshes with and drives an intermediate gear N shown in dotted lines in Figs. 3 and 5 which latter transmits power to the feed shafts and screws. These gears'uponthe shafts M and M are each provided with clutch mechanisms whereby different ones may be ut into engagement, thus changing the spee It is apparent from the foregoing descrip 40 tion that if thevertical shaft H is in motion and pull-gears R is slipped onto the outer end of cross-screw Q and meshed with intermediate gear N, and clutch K is thrown into driving contact with either of the clutch bev'el-gears L or L by means of clutch-lever K the cross-head will travel to the right or left on the transverse guide-ways, the direction of movement depending u on which of the bevel gears is being driven y clutch K;

g if pull-gear R is slipped onto the outer end of cross-rod R the cross-head saddle will re main stationary and its tool-slide will travel toward or away from the rotary-table, and at whatever angle thereto it may be set by means of the swlvel guide plate T, the direction of movement depending, as in the former case, upon whether clutch gear K is locked with gear L or L. On the other hand, if either-the cross-head or its tool-slide S are traveling along their respective guideways either may be thrown out of action by simply shifting clutch K into an inoperative position midway between gears L and L. As before stated, either the cross-head or its 5 tool-slide may also be operated along their respective waysby means of a crank handle placed upon the outer end of screw-rod Q or feed-rod R respectively.

The side-head is operated independently of the cross-head by means of the reversing and change-speed mechanism J. If pullgear 3 is slipped onto rod 77 and into mesh with intermediate gear N and clutch d is thrown into mesh with clutch-gear a, by means of shift-rod d the side-head will travel up or down the vertical guide-way Y, the direction of movement dependingupon whether clutch K is thrown into driving contact with clutch bevel-gear L or L. If clutch (Z is thrown into meshwith clutch- 80 sleeve e the tool slide 9 will travel toward or away from the rotary-table, and at whatever angle thereto it may be set by means of its swivel guide-plate h, the direction of motion dependlng, as in the former case, upon which of the two gears is being driven by the clutch K. If the side-head is traveling upon the vertical ways or the tool slide 9 upon its way either may be thrown out of action by either throwin the clutch cl into its normal position midway between the clutch-gears with which it operates or the clutch K into its normal osition between the clutch-gears with which it operates. As before stated, either the side-head or its tool slide may be 5 actuated by hand power through the n edium of the hand wheel 9, the pull gear 0 first being unmeshed from intermediate gear N and the clutch (1 locked with clutch gear a or worm sleeve clutch e.

Attention is called to the fact that the transverse section of the cross-rail, the cross head thereon, and the reversin and changespeed mechanism I through w 'ch the head I is operated form a combination of elements 5 which is entirely independent of a second combination comprisin the lateral section of the cross-rail, the si e-head thereon, and the reversing and speed changing mechanism J through which the side-head is operated, save that the two rail sections are united to gether by screws P. The advantages of this arrangement, which is one of the special features of my invention, lies in the opportunity thereby offered of equipping the ma- 1 1.-'- chine originally with the cross-head alone and of adding the side-head at a later period, if needed. The requirements of many urchasers are such that a cross-head mac no will amply meet them at the time ofpurchase, and .yet those requirements, throu h an increase of business or a change in t e character of work, may at a later date necessitate the employment of a cross and sidehead machine. That increased requirement may be readily met in a machine constructed as herein described and at a comparatively slight increase of cost, as the side rail and head, and mechanism for operating the head, may be added at any time. L

The method of using and operating the machine is as follows: The work is first attached to the rotary table or work-holder and the cross-head then adjusted to the proper height by raising the cross-rail upon the frame of the machine by means of hand wheel N. In raising the cross-rail the side head has also been raised and if further adjustment is necessary it can be secured by means of the hand wheel g or a crank handle, not shown, attached to the rod 6 the pull gear 0 being first pulled out of mesh and the clutch d thrust, by means of shift rod (1, into driving contact with spur gear a. The tools are then clamped in their respective toolholders and the tool-slides adjusted to the proper angle of cut by means of the swivel plates on which they are mounted. Further adjustment of the cross-head or its tool-slide may be secured by means of said crank handle a plied to feed-screw Q, or feed-rod R, and ther adjustment of the side-head or its tool-slide may be secured by hand-wheel g or said crank-handle applied to rod b the clutch'd being thrust into contact with gear a if the head is to be raised or lowered, and

pulled forward into contact with clutchsleeve 6 if the tool-slide is to be operated. The tools and slides having been brought into proper position, as for instance as shown in Flg. 2, the machine may be set in motion by manipulating the handle 7' which will set in motion the rotary-table or work-holder F and the vertical driving shaft H. By

means of the speed and clutch mechanism I and J the tools of each head may be driven independently in the direction and at the speed desired or the tool of either head may be operated alone.
